About this app

This app helps you estimate your blood alcohol concentration (BAC) over time after drinking.

By entering your basic information (such as height, weight, age and sex), the time you started
drinking, and the types and amounts of drinks consumed, the app calculates an estimated BAC curve.

You can view a simple table that shows how your estimated BAC may change in 30-minute intervals.

Important:
• All values are rough estimates only and can vary greatly between individuals.
• Actual BAC can differ depending on sleep, food intake, health conditions, medications, and many
other factors.
• This app must NOT be used to decide whether it is safe to drive, work, or perform any
safety-critical activity.
• The app is for personal reference and educational purposes only and is not a medical,
legal, or professional measurement tool.
